Background
The blockchain is a novel application mode of computer technologies such as distributed data storage, point-to-point transmission, a consensus mechanism and an encryption algorithm. The block chain (Blockchain) is an important concept of the bitcoin, is a decentralized database, and is used as an underlying technology of the bitcoin, and is a series of data blocks which are generated by correlation by using a cryptographic method, wherein each data block contains information of a batch of bitcoin network transactions, and the information is used for verifying the validity of the information and generating a next block. According to different application scenarios and user requirements, the Blockchain can be roughly divided into three major classes, namely Public chain (Public Blockchain), Private chain (Private Blockchain) and alliance chain (Consortium Blockchain). The most decentralized is the public chain. The private block chain is completely opposite, the writing authority of the network is controlled by a certain organization or organization, and the data reading authority is specified by the organization and is either open to the outside or has a certain degree of access limitation. A federation chain is a block chain between a public chain and a private chain, and "partial decentralization" can be achieved. Each node on the chain typically has a physical organization or organization corresponding to it; participants jointly maintain blockchain operation by authorizing to join the network and forming a benefit-related alliance.
